    I am using a generic Function that takes DynamicBuffer or NativeList as input. So I need to use INativeList.
    But there are not Add/Remove relative API on INativeList.
    Currently, I'm building Extension functions to implement Add/Remove on INativeList.
    Hope API can be added.
    most importantly: Add, RemoveAt, RemoveAtSwapBack.
    Also others like AddRange, RemoveRange...

    I guess it's possible to create generic code for Add because INativeList.Length has a setter, but there's no way to do AddRange in an optimized way.
    It would also be great to be able to create a NativeSlice from INativeList. If possible...

    As NativeList has an implicit cast to NativeArray you can simply do
    Code (CSharp):
    1. new NativeSlice<int>(list, 0, 10);
    2. // or
    3. list.AsArray().Slice(0, 10);
    You can add a 
    Slice
    extension to NativeList to get the same syntax as NativeArray.

    Yes, but I meant INativeList. So it's possible to use the same code for DynamicBuffer for instance.
